It's been no secret the pair haven't always seen eye to eye after first meeting on the set of the hit HBO series almost two decades ago.

And during an interview with Piers Morgan for ITV's Life Stories this week, the actress said SJP "could have been nicer" during their time on the show.

Last week, Sarah Jessica Parker said she was "disappointed" that a third movie wouldn't be going ahead.

The Hollywood star, who played sex columnist Carrie Bradshaw, said that a script had already been written for a sequel but it will not make it to the big screen.

"It's over. We're not doing it," the 52-year-old told Extra TV.

"I'm disappointed. We had this beautiful, funny, heartbreaking, joyful, very relatable script and story.

"It's not just disappointing that we don't get to tell that story and have that experience, but more so for that audience that has been so vocal in wanting a third movie."

The original six-season TV show ran for six years between 1998 and 2004, following the lives of Carrie, Samantha (Kim), Charlotte (Kristin Davis) and Miranda (Cynthia Nixon) as they struggled through the world of dating.

The leading foursome reunited when the show was transformed into a feature film in 2008, with a second two years later, both directed by Michael Patrick King.
